- 27. Selenium suite of tools Selenium suite • Developed by Shinya Kasatani • Firefox or Chrome extension that can automate the browser functionality • Records user interactions on the browser and exports them as a reusable script • Selenese commands can be used to modify the test script generated after recording • Selenium IDE deploys on Windows, Linux, and MacOS platforms Selenium Integrated development environment (IDE)
- 28. Selenium suite of tools Selenium suite Selenium Integrated development environment (IDE) • Selenium IDE ceased to exist in August 2017 • A robust version of IDE was released in 2018 by Applitools • The new IDE deploys a Selenium Side Runner that allows all IDE tests to run on any browser, in parallel, and on a grid without needing to write any code. • Selenium IDE is integrated with other suite components to provide a robust interface for application testing
- 29. Selenium suite of tools Selenium suite Record and playback feature
- 30. Selenium suite of tools Selenium suite Selenese commands showing the actions performed on the browser
- 31. Selenium suite of tools Selenium suite Log indicating the execution of every command
- 32. Selenium suite of tools Selenium suite Saves the executable script in the side format
- 33. Selenium suite of tools Selenium suite Selenium Remote Control (RC) • Paul Hammant developed Selenium RC • Selenium RC is a server written in Java • RC makes provision for writing application tests in various programming languages like Java, C#, Perl, PHP, Python etc. • The RC server accepts commands from the user program and passes them to the browser as Selenium-Core JavaScript commands • The browser behaves accordingly
- 34. Selenium suite of tools Selenium suite Selenium Remote Control (RC) RC Server Web browser injected with Selenium core Selenium test script
- 35. Selenium suite of tools Selenium suite Selenium Remote Control (RC) test.js RC Server Web browser injected with Selenium core • Consider a JavaScript program test.js used by google.com. • The program can access pages within google.com like google.com/mail, google.com/login
- 36. Selenium suite of tools Selenium suite Selenium Remote Control (RC) test.js RC Server Web browser injected with Selenium core • However, it cannot access elements of other domains like yahoo.com • Local copies of Selenium core and the web browser had to be installed so that they belonged to the same domain
- 37. Selenium suite of tools Selenium suite Selenium Remote Control (RC) test.js RC Server Web browser injected with Selenium core This is called Same Origin Policy and Selenium RC was introduced to address this limitation. The server acts as a client configured HTTP proxy and "tricks" the browser into believing that Selenium Core and the web application being tested come from the same origin
- 38. Selenium suite Selenium WebDriver • Simon Stewart developed WebDriver in 2006 • The first cross-platform testing framework • Programming interface to create and run test cases • Makes provision to act on web elements • Does not require a core engine like RC and interacts natively with the browser applications • Supports Java, C#, PHP, Python, Perl, Ruby, etc. • Supports frameworks like TestNG, JUnit, NUnit Selenium suite of tools
- 39. Selenium suite of tools Selenium suite Selenium WebDriver Selenium WebDriver does not require an additional RC. It directly interacts with browser and controls its working
- 40. Selenium suite of tools Selenium suite Selenium Grid • Developed by Patrick Lightbody • The main objective of Grid is to minimize test execution time • Grid was designed to distribute commands to different machines simultaneously • Selenium Grid allows the parallel execution of tests on different browsers and different operating systems • Grid is exceptionally flexible and is integrated with other suite components for simultaneous execution
- 41. Selenium suite of tools Selenium suite Selenium Grid The Grid consists of a hub connected to several nodes. It receives the test to be executed along with information about the operating system and browser to be run on
- 42. Selenium suite of tools Selenium suite Selenium Grid The hub picks a node that conforms to the requirements (browser and platform) and passes the test to that node
- 43. Selenium suite of tools Selenium suite Selenium Grid The node runs the browser and executes the selenium commands within it
